Mrs. Dominick's class conducted a survey on the number of chores students completed, and the amount of allowance they earned. Bryan thinks the association is negative because they found that as the number of chores decreased, the amount of allowance also decreased. Is Bryan correct?
a. Bryan is correct because if one of the variables is negative, then the association is negative.
b. Bryan is incorrect because if the variables move (or change) together, then the association is positive.
